“…Metallic and metal oxide nanoparticles are important for these applications due to their features such as tunable optical properties, biocompatibility, feasible surface functionalization and negligible cytotoxicity, etc. [9][10][11][12][13][14][15][16][17][18].…”

In the present work, zinc oxide nanoparticles (ZnO-NPs) were synthesized in the presence of poly(ethylene glycol) which is a biocompatible agent in living systems. The sub-chronic effects of ZnO-NPs were investigated based on biochemical parameters and histological changes applied to Rattus norvegicus. The structural, morphology, and size characterization of nanoparticles were studied by applying techniques as XRD, SEM, FTIR, and TEM. 8-week intraperitoneal injection of ZnO-NPs at a dose of 100 mg/kg leads to significant changes in liver enzymes, malondialdehyde (MDA) content, and tissue histopathological changes. The animal group which was treated with 50 mg/kg of ZnO-NPs presented elevated blood urea nitrogen and creatinine levels, but the liver enzymes and liver histopathology were found to be in normal level. The rats exposed to increasing dose of ZnO-NPs (100 mg/kg) showed necrosis of germinal epithelium and sertoli cells in the seminiferous tubules. The current study clearly demonstrated the dose-dependent toxicity of zinc oxide nanoparticles.

“…The XRD data were analyzed using the commercial X'pert HighScore package. Identification of structure type using X'pert HighScore confirms that all the diffraction peaks of the XRD pattern for the MgMnO 3 can be quite well indexed to a defect cubic spinel-type structure (JCPDS, 28-0625) with space group Fd3m and for the SrMnO 3 to hexagonal structure (JCPDS, 00-024-1213) with space group P63/mmc (Khedri and Gholizadeh 2019;Bhattacharya et al 2008;Thota et al 2012). Generally, relationship between the inter-planar d spacing of the plane with Miller's indices (hkl) for hexagonal system and Bragg…”

Spinel-type oxide MgMnO 3 and perovskite-type oxide SrMnO 3 have been synthesized by two-step procedures comprising the hydrothermal and solid-state methods. The as-prepared catalysts were characterized by X-ray powder diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis and the morphologies of the synthesized materials were figured out by field emission scanning electron microscopy. The catalytic performance of synthesized materials were investigated by synthesizing the polyhydroquinolines, which was used Design-Expert software and response surface methodology (central composite design) for optimization of reaction efficiently. The comparison study illustrates that MgMnO 3 has better catalytic performance than SrMnO 3 and optimized condition for the synthesis of polyhydroquinoline (which is produced by the reaction of ethyl acetoacetate, benzaldehyde, dimedone and ammonium acetate) was found to be 8 mg of MgMnO 3 as the catalyst, 33 min for the reaction time and 100°C for the reaction temperature. This condition was used for the synthesis of other polyhydroquinoline derivatives.

A facile hydrothermal method was used for fabricating phase-pure Bi1-xCexFe1-xZrxO3 (x = 0.00, 0.03, 0.06) multiferroic ferrites, and the dependence of structural, optical, and magnetic properties on the composition have been investigated. The samples were investigated by X-ray diffraction (XRD), Raman and Fourier-transform infrared (FT-IR) spectroscopies, scanning electron microscopy, UV-Vis spectroscopy, and vibrating sample magnetometer at room temperature. Structural results show that the structure of Bi1-xCexFe1-xZrxO3 ferrites is indexed to a rhombohedral structure with R3c space group. However, the weakening in the intensity, the expansion of the line-width of all bands, and some band shifts observed in Raman spectra indicate a structural transition from rhombohedral (R3c) to pseudo-tetragonal (P4mm) phase as the content of Ce/Zr increases. Also, a significantly enhanced intensity of the A1-2 mode in Raman spectra means that there is a novel behavior of magnetic anisotropy in the Ce/Zr cosubstituted samples. A significant increase in optical band gap with increasing of the Ce/Zr cosubstitution suggests that the materials are suitable for technological applications. Magnetic properties of the samples show a magnetic transition from antiferromagnetic to ferromagnetic phase due to the presence of the rhombohedral to the tetragonal phase transition, and exchange interaction between the 4f orbitals of the Ce 3+ /Ce 4+ and the 3d orbitals of the Fe 3+ /Fe 2+ .
